Technical Data
NIBCO bronze ball valves installed with NIB-SEAL insulated handles are the only approach that keeps your
insulated piping system completely intact.
The revolutionary NIB-SEAL bronze ball valve stops condensate cold. Its unique thermal barrier design keeps moisture from infiltrating
your insulated system while preventing thermal energy loss through exposed metal handles.
Designed for new installations or retrofitting existing systems, NIB-SEAL bronze ball valves offer a wide range of advantages for typi-
cal commercial HVAC systems as well as industrial applications where insulated piping is desirable.
• Protective sleeve provides a stationary surface to affix the insulation, allowing operation and maintenance of the valve without
destroying the integrity of the insulated system.
• High-strength cylindrical handle design features easy access to standard adjustable memory stop for system
balancing. The valve packing is also readily accessible for routine maintenance.
• Cap and insulating plug provide a vapor seal to prevent exchange of air to maximize the efficiency of your insulated piping system.
• Position indicators allow at-a-glance determination of whether valve is in open or closed position.
• Pre-formed hole allows for convenient tagging.
